Usually, there are five intermediate lines after each index line. Ii) Intermediate lines are thinner lines between the index lines. They are the thickest contour lines and are usually labelled with numbers. I) Index lines show the elevation of a place above sea level. Therefore, the correct answer is Option A. Since three types is the correct answer, this is an incorrect option. Seven different types of lines would again be too confusing and make the map way more complicated than needed. Only two types of lines wouldn't be enough to properly provide all the information in the map. They are the Index lines, Intermediate lines and the Supplementary lines. Contour lines are of three different kinds. The different kinds of contour lines are instead used to show different aspects of the same parameter (most commonly the altitude).Ī. Whether the contours represent altitude or some other parameters is clearly stated in the key. But the way the lines are drawn are the same. Sometimes it is also used to show places with the same temperature or pressure. These maps use contour lines to show places with the same elevation.ĭue to the extensive use of contour lines, topographical maps are also known as contour maps.Īs mentioned earlier, contour lines are used in topographical maps to connect all the places with the same elevation. They are maps of relatively smaller areas but with very detailed and extensive information about it. Negative space drawing.Hint: Topographical maps are maps that show the shape and features of the surface of the earth of any particular area. Now that you know what contour line is and how it can help your drawing let’s take a lookĪt the flip side of the contour coin. Look at the both the outer and dominant inner contours of your subjects to see if they are interacting negatively with each other. When setting up a still life to draw look at the outline shape to pick the most interesting angle of your subject.īe aware of bad tangencies (the line of one object awkwardly running into another object)Įven if you have drawn beautiful subjects, tangencies can easily wreck your drawing and make it look wrong. We will talk about composition in detail later but here are some good tips to remember. Inner contour elements different ways until you find just the right level of detail forĪnother very important use of the contour is with composition.

We will get into detailed lessons about shadows in Drawing Essentials: Level 3. Shadows are their own element and are very important in showing the form of objects. I don't consider shadows to be contour lines at all.
